Is it normal for coleus cuttings to wilt before roots?
Comments (6)Your medium needs to be coarse textured and moist. Make your cuttings about five inches or less. Remove the bottom leaves, keeping only the top two or so; pinch off any flowers if present. If those leaves are large, you can snip off half to reduce the surface area. Pre-drill holes with a pencil or skewer, place the cutting into the hole and water again to force the mix around the stem. No pinching, poking, or tamping with your fingers. Place your cuttings in a shaded location, out of the heat but not in frigid air conditioning. You can certainly cover with plastic to reduce transpirational loss during the rooting period. Don't pull on the leaves to check on their progress for at least three or four weeks. If the medium that you are using is overly peaty and dense then you may want to add fifty percent perlite. I always prefer rooting in a medium of some sort, rather than water....See Moreblack roots, yellow roots, dried up roots
Comments (5)The plant is in pretty good condition, it is normal for old roots to rot off and die. Provided the plants grows new roots at regular intervals all will be well. You need someone to tell you how often to repot Phalaenopsis. Tell us where you have the plant and the temperature ranges there, to provide clues re. No flowers....See MoreCacti has stem buried. This normal?
Comments (15)Yeah I bought it from this Cactus nursery. The man had been growing cacti for over 40 years now. Apparently he uses such a complex mix, it has 9 different ingredients, I don't know why. Mostly it's river sand and different parts of Compost like goat and cow droppings etc etc. But yeah it's mostly a lot of river sand. Should I always wash off the small particles stuck onto the roots like that? I was scared of damaging the roots so I left what was really stuck onto the root hairs....See MoreRoots or STEM Size
Comments (5)Hi a1an, " ...did try doing some annual seed germination one year. This is with those lights that those - mary jane- growers use. It was insane....I got a headache from entering the -grow room- setup as the lights were that intense. " Many of the marijuana growers use a mix of red and blue lights, because those are the parts of the spectrum that plants need. Plants are green because they don't need green light, and reflect it. The red and blue lights combine to create a hideous purple light. I definitely will not tolerate purple light for growing plants indoors, even though the plants may like it. I much prefer daylight white light, and my fluorescent tubes are a mix of cool white, warm white, and a few extra warm tubes that produce light very similar to incandescent bulb light -- kind of a yellow-orangish tint that gives plants a dose of red that they like and doesn't bother me because it is mixed with a lot of white light. " Still have like 3K in lights lying around....but it was more a one time experiment . It's too much -work- sowing indoors... " That's a lot money tied up in lights. I totally enjoy both outdoor growing and indoor growing. But I confess to being a little weird in that regard, because I actually get some enjoyment out of washing pots. That's sort of like enjoying washing dishes. But the indoor growing lets me continue my zinnia breeding indoors during the Winter. Zinnias grow fast, and I can get two generations of zinnias indoors in addition to two generations outdoors. So four generations of zinnias per year contributes to making some significant breeding progress. I have several zinnia flower forms that are not available commercially. This is an example. Click on the pic to see a larger version. Those petals are tubes, which changes the look of the flower. By making many crosses between my hybrids, I can rearrange genes to get new forms of zinnias. Recent advances in lighting technology have improved indoor gardening. However I am still using T8 fluorescent lights, because I have them. When I first started indoor growing in 2005, T8 lights were considered modern. But not anymore. However, they still work fine, partly because they are rated at 20,000 hours per tube and partly because I have learned to overdrive them to increase their brightness significantly.
